Patrick drifts off to Noisette Street at an unknown point in time, being taken in by Liam. His cheery demeanor made him easily acceptable, especially among Evee and Maureen.

He is especially significant for his cooking skills, making the food and keeping the morale up of his companions. He has the friendliest first interaction with Julius Petero, quickly advising him as they burned the bodies of the apartment's dead tenants.

He would cook for the group for two more nights, until he learned that Maureen's boyfriend, Duane, had a truck set up for them as rescue. He tags along with the group, and does his best to protect each and every one of them. He later earns a bite from a walker but decides to keep it from the group, hoping to reveal it when time comes.

When they finally arrive, Patrick chose to stay behind so that Maureen, Evee, and Duane could have a clean escape. He fought the soldiers head-on, and manages to flee, but at the cost of sustaining more injuries.

He later encounters Julius, who urges him to keep on moving. Julius wonders why he's not following, and he reveals him his bite. Julius was forced to flee, leaving the infected Patrick alone.

Patrick's final character varied widely from his original counterpart. He was supposed to be Barbara's troublesome son, who would focus only on survival and himself. Later on, his relation to Barbara was severed and he was made into a homeless man, found by Liam in the streets. His personality would be much more bizarre than his current one. His role as a heroic sacrifice would still be upheld.
